A high-stability optical clock based on a continuously ground-state cooled Al ion without compromising its accuracy
Fabian Dawel, Lennart Pelzer, Kai Dietze +12
Single ion optical clocks have shown systematic frequency uncertainties below , but typically require more than one week of averaging to achieve a corresponding statistic…

Entanglement-enhanced optical ion clock
Kai Dietze, Lennart Pelzer, Ludwig Krinner +11
Entangled states hold the promise of improving the precision and accuracy of quantum sensors. We experimentally demonstrate that spectroscopy of an optical clock transition using e…
